I have not seen this plant, the leaves of which appear to have been unknown to 

 Engler, but I think it probable that speoiraens in leaf and fruit collected by Wel- 

 witsch may belong to this species ; I therefore give the following description, com- 

 piled from the specimen and notes made by Welwitsoli in the British Mnstmm : 

 Rhizome fleshy, with thick, flesh}-, simple roots. Leaves appearing after the flowers, 

 green above, glaucous-pruinose beneath, glabrous ; petiole 5-6 in. long, spotted with 

 purple ; blade 4-5 in. long, 2f— 3^ in. broad at the insertion of the petiole, deltoid- 

 or ovate-deltoid-sagittate, shortly and rather abruptly acuminate ; basal lobes broadly 

 deltoid, obtuse, with a broad triangular sinus ^-1\ in, deep between them ; veins 

 very conspicuous. Spathe and spadix not seen. Peduncle short. " Berries densely 

 glomerated in a shortly pedunculated head, subterranean, white, angulate-sub- 

 pyriform, umbonate with the remains of the stigma, 2-celled, cells 1-seeded {Wel- 

 witsch)." — Stylochiton natalensis, Engl. Araceae No. 71. S. natalense, Rendle in

9. S. hypogaeum, Leprieur in Ann. Sc. Nat. ser. 2, ii. 185, t. 5. 

 Rhizome horizontal, about h in. thick, fleshy, with thick fleshy simple 

 roots. Leaves 5-8 to a plant, contemporary with the flowers ; petiole 

 3-6 in. long, yellowish-green spotted with purplish-violet, the sheathing 

 part subterranean ; blade hastate or hastate-sagittate, as long as the 

 petiole ; front lobe oblong-lanceolate, acuminate ; basal lobes somewhat 

 spreading, oblong acute, about J as long as the first lobe. Spathe very 

 shortly pedunculate, arising from the rootstock by the side of the 

 leaves, 2 in. long : tube subterranean, cylindric,, slightly inflated at the 

 base ; limb ovoid, acute, with a narrow mouth on one side. Spadix 

 shortly protruding from the mouth of the spathe. Female flowers G-0 

 or more (in one cycle ?), adnate to the base of the spadix, connate. 

 Perianth adnate to the apex of the ovary (?), with a short free oblique 

 urceolate limb. Ovary inferior (?) ; style moderately slender, much 

 exserted, erect, " articulated " (thickened) below the middle. Fruit sub- 

 terranean, consisting of the connate ovaries, fleshy, included in the 

 dilated base of the spathe. — Blume, Rumphia, i. 88 ; Kunth, Enum. iii.
